WINDOW-HOLDER.

Specification of Letters Patent. Patented Sept. 21, 1920.

Application filed August 12, 1916. Serial No. 114,603.

To all whom it may concern:

Be it known that I, THOMAs J. HEADY, a citizen of the United States, residing at Cottonwood, in the county of Yavapai and State of Arizona, have invented certain new and useful Improvements in Window-Holders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to window holders, and the primary object of the invention is to provide a holder which is extremely simple in construction, efiicient in operation and which may be manufactured for a minimum cost.

A further object of this invention is to provide a holder as specified, which includes a rotatably mounted disk or 0am which is rotatably mounted upon the upper edge of the mid-rail of a lower window sash, and which is adapted for seating in notches formed in a notched bar which is carried by one of the side rails of the upper sash of a window for holding either the lowersash in a raised position, the upper sash in a lowered position, or both, or for holding both sashes closed against accidental or malicious opening.

With the foregoing and other objects in View this invention consists in such novel features of constructions, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters designate like and corresponding parts throughout the several views, and in which Figure l is a fragmentary view of a window showing the improved holder applied thereto.

Fig. 2 is a fragmentary vertical section through the window showing the holder applied.

Fig. 3 is a fragmentary horizontal section through the window showing the holder applied.

Fig. 4 is a cross section through the supporting wear plate, and

Fig. 5 is a plan view of the wear plate.

Referring more particularly to the drawings, 1 designates a window structure of ordinary make, which slidably supports an upper sash 2 and a lower sash 3.

The mid-rail 4: of the lower sash 3 has, a wear plate 3 attached thereto by a plurality of screws 3", which extend through openings 3 formed in the plate 3 The wear plate 3 is mounted upon the upper edge of the lower sash 3 adjacent to one end of the same, and it has an upstanding pin or bolt 3 carried thereby and projecting upwardly from its central axis, which bolt rotatably supports a locking cam 5. A nut 3 is fitted upon the bolt 3 and serves to hold the cam 5 against accidental displacement. The cam 5 has a slightly curved finger 6 projecting outwardly from the periphery of the same which is provided for facilitating the inanual movement or rotation of the cam. The upper surface of the wear plate 3 is concaved, as at 3, to receive the convexed lower surface 5 of the cam 5 to form a bearing surface for the same. The marginal edge of the cam is beveled as is shownat 7 for seating in the notches 8 which are formed in a bar 9. The bar 9 is attached to the side rail 10 of the upper sash 2, and it is provided with a plurality of the notches 8 which are spaced longitudinally along the length of the bar so as to permit the holding of the upper and lower sashes 2 and 3 in various adjusted positions with respect to each other and to the window frame or oasing I. V The cam 5 is oval shaped, so that it may be rotated to permitof a free and independent movement of one of the sashes with respect to each other.

In reducing the invention to practice, certain minor features of construction, combination and arrangement of parts may necessitate alterations to which the patentee is entitled provided such alterations are comprehended within the scope of what is claimed.

What is claimed is In a window holder and lock, the combination with an upper and a lower sliding sash, of a wear plate secured to the mid rail of the lower sash and having an upper concaved surface, an oval shaped cam rotatably carried by the wear plate and covering the concaved surface thereof, a. bar carried by one side of the upper sash having a plurality of V-shaped notches therein, said cam being adapted for extending into any one of said notches for holding the sashes in various positions, said cam having the upper and lower edges oi the periphery thereof beveled. in opposite directions to conform to the configuration of the notches, and permit the easy insertion of the cam therein, as ,and for the purpose specified.

In testimony whereofI aflix my si nature in presence of two witnesses.

THOMAS J. IiiEADY.
